  • Production and recovery of tyrosinase from melanin-synthesizing bacteria
    Patent number: 5451515
    Abstract: The present invention relates to the discovery of a new bacteria of the genus Alteromonas which has been found to attract oyster larvae by the production of compounds involved in melanin synthesis. More specifically, the present invention contemplates a method for inducing the settlement and metamorphosis of Crassostrea virginica larvae by induction with certain metabolic substances produced by the present bacteria and its altered variants. Furthermore, the present invention is directed to other and derivative metabolic products which can be employed for their desired utility and application. In accordance with the present invention, it has been discovered that ammonia (NH.sub.3) initiates settlement and metamorphosis of the oyster larvae in the same manner as the natural phenomena.
    Type: Grant
    Filed: April 15, 1994
    Date of Patent: September 19, 1995
    Assignee: Research Corporation Technologies, Inc.
    Inventors: Ronald M. Weiner, Rita R. Colwell, Dale B. Bonar, Steven L. Coon, Marianne Walsh

  • Induction of settlement and metamorphosis in Crassostrea virginica by melanin-synthesizing bacteria
    Patent number: 4740466
    Abstract: The present invention relates to the discovery of a new bacterium, alteromonas calwellii, which has been found to attract oyster larvae by the production of a compound involved in melanin synthesis. More specifically, the present invention contemplates a method for inducing the settlement and metamorphosis of Crassostrea virginica larvae by induction with certain metabolic substances produced by the present bacterium and its mutagenically altered variants. Furthermore, the present invention is directed to other and derivative metabolic products which can be employed for their desired utility and application.
